Filtration Media / Application Guide (hydrophobic or hydrophilic) 

Glass microfiber filter media - prefilter versions available in all variations

+ Mixed Cellulose Esters (MCE) - Hydrophilic - Mixed Cellulose Esters (MCE) - Hydrophilic
  • • This membrane is recommended for all filtrations in aqueous or polar media, bacteria filtration
  • • Ideal when maximum protein recovery in filtrate is crucial
  • • Used for filtration and inspection of gas, oil and alcohol particulate and bacteria
  • • Combined with glass microfiber prefilter, ideal for tissue culture media and sensitive biological samples
  • • Sample filtration - prefilter increases yield

+ Cellulose acetate (CA) - Hydrophilic - Cellulose acetate (CA) - Hydrophilic
  • • Very low binding capacity for proteins.
  • • Material is nitrate-free making it suitable for groundwater & EPA ASTM’s.
  • • For filtration under sterile conditions
  • • Filtration and clarification of biological fluids, sterilization of media additives and serum
  • • Sample preparation of aqueous solutions
  • • For applications requiring maximum sample recovery
  • • Sample preparation of protein-based HPLC solutions
  • • Designed to sterilize and remove particulates from even the most viscous proteinaceous samples
  • • Filtration of tissues culture media with glass fiber prefilter

+ Polyamide/Nylon (PA) - Hydrophilic - Polyamide/Nylon (PA) - Hydrophilic
  • • Hydrophilic material; it is recommended for filtration of aqueous or organic/aqueous medium polar liquids.
  • • Commonly used for general laboratory filtration and filtration of HPLC and GC samples prior to injection
  • • Filtration of aqueous and organic-aqueous polar medium liquids
  • • Dissolution sample analysis
  • • Suitable for use with high pH samples
  • • Since it binds proteins it is NOT suitable for protein recovery applications
  • • With microfiber prefilter higher absorption capacity for contamination

+ Polyethersulfone (PES) - Hydrophilic - Polyethersulfone (PES) - Hydrophilic
  • • High filtration flow rates
  • • An inherently low affinity for proteins.
  • • Low extractables
  • • Introduction of additives into tissue culture vessel.
  • • Certified for Ion Chromatography
  • • Final filtration of bacteriophage and infusion solutions
  • • Tissue culture, proteins, buffer and nucleic acids filtration
  • • Ideal for applications requiring maximum sample recovery
  • • Filter hybridization solutions and probe to reduce backgrounds
  • • Food, beverages and ultra pure water final filtration
  • • Sterile product individually blister packed

+ Polyvinylidene difluoride (PVDF) - Hydrophobic - Polyvinylidene difluoride (PVDF) - Hydrophobic
  • • This membrane features a stability and hydrophobic interactions similar to PTFE.
  • • Recommended especially for filtration of water-soluble oligomers and polymers, e.g. protein solutions.
  • • Can also be used for the filtration of hydrophobic substances in different organic solvents.

+ Polytetrafluoroethylene (PTFE) - Hydrophilic or Hydrophobic - Polytetrafluoroethylene (PTFE) - Hydrophilic or Hydrophobic
  • • PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases.
  • • Very resistant to solvents as well as acids or bases.
  • • Can be made more hydrophilic by flushing with alcohol, followed by water
  • • Used for filtering and de-gassing chromatography solvents
  • • Permits optimal utilization of small sample volumes
  • • Excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials
  • • Moisture barrier for venting applications and vacuum pump line protection
  • • Ideal for aerosol sampling
  • • Filter viscous organic based HPLC samples
  • • Glass microfiber prefilter raises absorption capacity and loading
  • • After pre-wetting with alcohol, may be used for fine particle removal of aqueous and mild organic solutions in Ion Chromatography

+ Glass Fiber Prefilters - Glass Fiber Prefilters
  • • For viscose solutions or for turbid liquids
  • • Ideal for use as a prefilter in series with other syringe filters
  • • Glass microfiber filter media enclosed in this series is binderless 1.0µm retention
  • • Reduces clogging of the membrane, so ideal as a prefilter to increase throughput and flow rate
  • • Ideal for dissolution testing and general filtration
  • • Applicable to all membrane types, allowing higher flow rates
  • • Good compatibility with strong acids, bases and organic solvents
  • • Similar in composition to binderless borosilicate glass microfiber media available as disks and sheets
